drive in Channel 1, Bay 1 has a drive state of online (ONL) and is part of Array A. Notes 1. The Array/Bay selection list does not reflect the physical configuration of the server. (See "Internal Drive Bays" on page 197 for the physical location of the hard disk drives.) 2. The SCSI IDs for the hot-swap hard disk drives is set by the backplane. The backplane allows you to define the IDs as low (0 to 5) or high (8 to 13). See "SCSI Backplane Option Jumpers" on page 249 for more information about setting jumpers on the backplane. 3. The bay number corresponds to the SCSI ID of the device plus 1. For example, the ServeRAID controller (INI) uses SCSI ID 7 and its bay number is 8 (7 + 1). 4. Bay Number 8 (SCSI ID 7) is reserved for the ServeRAID controller (also known as the initiator, INI); therefore do not set the SCSI ID of non-hot-swap device, such as a tape drive, to 7. 4 The Array list indicates the array IDs and the sizes (in megabytes) of the arrays. When a drive is being rebuilt, this list and the Logical Drive list show the progression of the rebuild process. 5 The Logical Drive list shows the size, RAID level, status, and write policy for each logical drive. (See "Logical Drive States" on page 88 for more information.) 6 This area provides information and instructions about the actions you can perform on the current screen or pop-up window. Physical Device States: Descriptions of the physical device states, which appear in the Array/Bay selection list, are as follows: State Meaning CDR A CD-ROM drive is installed. DDD The physical hard disk drive is defunct (DDD). A drive in the Online (ONL) or Rebuild (RBL) state has become defunct (DDD). It does not respond to commands, which means that the ServeRAID controller cannot communicate properly with the drive. A hard disk drive in the DDD state does not necessarily mean that you need to replace the 86 Netfinity Server HMM
